RESIN COMPOSITION CONTAINING STARCHY MATERIAL

摘要

[Problem] To provide a molding material having good affinity to a starchy material, is homogeneously compatible therewith even without adding compatibility-imparting agent, can be favorably mold-worked despite the starchy material is blended in large amounts, and features excellent balance between the flexibility and the mechanical properties, as well as excellent moisture permeability, antistatic property and transparence (haze) depending upon the composition that is used. [Means for Solution] A resin composition comprising 10 to 97% by weight of at least one (A) of those selected from an ethylene copolymer containing an unsaturated carboxylic acid and an unsaturated carboxylic acid ester as constituent units or a copolymer composition thereof, and an ionomer comprising, as a base resin, the ethylene copolymer containing the unsaturated carboxylic acid and the unsaturated carboxylic acid ester as constituent units or the copolymer composition thereof; and 3 to 90% by weight a starchy material (B).
